Most airlines will allow you to check one bag and have one carry-on bag. There is normally a maximum weight limit of 50 pounds per checked bag as well as a size restriction. The most common maximum size bag allowed is 62 linear (total) inches. A common size bag for checking through is: 27 x 21 x 14.

In 2026, the standard rules for checked baggage on international flights generally allow for a weight limit of 23 kg (50 lbs) for Economy Class and 32 kg (70 lbs) for Business or First Class. The total linear dimensions (length + width + height) must not exceed 158 cm (62 inches). Most full-service carriers on long-haul routes include one or two pieces in the fare, but "Basic Economy" or "Light" fares often require a separate fee for any checked items. It is strictly prohibited to pack lithium power banks, loose batteries, or flammable liquids in your checked luggage due to fire risks in the cargo hold; these must stay in your carry-on. Additionally, new 2026 customs regulations in many countries (such as India's "Baggage Rules 2026") have updated duty-free limits, now allowing residents to bring up to ₹75,000 worth of goods and specific weight-based gold allowances. To avoid expensive "airport rates," travelers are strongly advised to weigh their bags at home and pre-purchase any extra weight online at least 24 hours before departure, as gate-check fees have increased significantly across the industry this year.
